boot process; listing drivers that loaded and drivers that did not. Enable low resolution video - Disables the default graphics driver and uses the standard VGA driver. Intended in case the user changed the resolution to an unusable level (i.e. 320×200 at low refresh rates <24 Hz, 60 Hz>) Last Known Good Configuration - Loads configuration based on the last successful boot process. Intended for Registry corruptions. This mode is removed in Windows 8 and later versions of Windows. Directory Services Restore Mode - Boot mode used to reboot the Domain Controller in case it is not working as intended. Debugging Mode - Boots while loading the kernel debugger. Disable automatic restart on system failure - Disables the auto-reboot function after a Blue Screen of Death is experienced.

Disabling ELAM is intended to allow booting on false positive driver checks but could also allow a tampered driver to load. Disable Driver Signature Enforcement - Disables the kernel setting that prohibits unsigned drivers from loading.
